"I do, and I do it well."
Numerous studies have been done that demonstrate that people consistently overvalue their contribution/abilities. But that's not on-topic, so enough of that.
I will absolutely grant you that there are a many, many cases where someone's ends may be served by plopping down unrepresentative software onto unrepresentative hardware, call it test network, don't care about the difference, and may not be any the worse for it.
However, there *are* a large class of problems and are in *no* way served by this. It's not a matter of not appreciating "free stuff", as I certainly do. But a test network that shares nothing in common with my production network isn't work squat. It's probably that we're just working at substantially different tolerances.
